“…Erbium-doped fiber amplifier (EDFA) has been extremely compatible to both low and high bandwidth communication networks [1]. In order to cope with the bandwidth demand, new EDFAs has been proposed to provide high gain and to fully utilize the redundant fiber bandwidth [2,3]. Wavelength division multiplexing (WDM) systems with terabits per second capability together with EDFA has been installed in submarine networks [4] anticipating this bandwidth explosion.…”

Abstract:We propose a new pumping method for optical fiber amplifiers at 1480 nm and 980 nm that is able to provide high gain and low noise-figure. The gain and noise figure obtained were 38.3 dB and 5.5 dB with an improvement of 3.8 dB and 1.4 dB, respectively, at 1550 nm, for −30 dBm input power when compared to its counterpumped design. This design also delivers higher gain and lower noise figure when compared to the common bi-directional dual-pumped designs. A power conversion efficiency of 44.5% was achieved in this design.

“…3. In a general case of EDF amplifier, the saturated pumping power is ∼20 dB m [5]. In the case of MLL, therefore, the generation of 1550-nm fluorescence is almost power-independent.…”

In this paper, we demonstrate a high‐power erbium‐doped fiber amplifier pumped by single‐mode titanium sapphire (Ti:S) laser at 980 nm. The highest output power of 22.6 dBm is measured at 1549 nm with an input signal power of 4 dBm and a pump power of 300 mW. This corresponds to power‐conversion efficiency (PCE) of 60%, providing 95% quantum efficiency. The experimental results show the feasibility of using a single‐mode laser from a high‐power semiconductor chip to produce high‐efficiency booster amplifiers. © Wiley Periodicals, Inc.
